This was the first part of spaceballs that I ever saw, then I saw the whole movie later. If you dont know, this part was actually makeing fun of 2 things: The alien bursting out of that guys chest was makeing fun of the movie "Alien", and the "Hello My Baby" thing was from "Lunnie Toons"(orginally it was a dancing frog.)The one word I would use to describe this is; "Rolf".
